Im thinking about replacing my ps1000 with a 15'' titanic sub. my ? is can i hook my ps1000 up to my 2 channel khl reciever [ bedroom system] which has no sub output. It does how ever have pre-outs and pre-ins hook ups, can i some how use them. The manual shows a few different ways of hooking the sub up but im not sure if i understand what there saying. Btw does anyone think the 15'' titanic will put the ps1000 to shame, I HOPE.
